So, I just updated the software to the new 1.10, went outside to test drone act weird, like drifting to left, and got the motor error, landed drone and it was kicking both rear  motors, replaced both propellers and error went away ! One thing I could  figure out was, that when the drone is put back on the case, those rear  propellers if they are not well aligned, they will touch the botton of the case and the guimbal protector and they will bend or damage, I  think this is a flaw on the project, the front and the back of the drone should be a little higher on the botton when folded to allow space for the propellers don't touch the botton of the case, and also a little more space between the propellers and the bottom body of the drone!
